Abstract
An isocyanate-based elastomer containing a filler material, the filler material being present at a level in the range of from about 30% to about 90% by weight of the elastomer and having a specific gravity of less than about 2.0. A process for producing the isocyanate-based elastomer is also disclosed. The process comprises the steps of: providing a first mixture comprising a catalyst and a filler material, the filler material being wetted by the catalyst; providing a second mixture comprising an isocyanate and an active hydrogen-containing compound; mixing the first mixture and the second mixture to provide a reaction mixture; allowing the reaction mixture to react to produce the isocyanate-based elastomer.
